Application [ilcd September 8, 1887. Serial No. 249,088. (No model.)

To all whom it may concern.'

Beit known that l, WILLIAM A. CAREY, of Malden, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Lubricators, of which the following is aspecification.

This invention is an improved lubricator or oil-cup, whereby oil may be applied to bearings and its flow regulated.

In the accompanying drawings, in which similar' letters of Nreference indicate like parts, Figure l is a vertical section of my device with the valve-stem raised. Fig. 2 is a vertical section of the upper portions with the valve-stem represented as broken off. Fig. 3 is a vertical section of the device with the valve-stem down and the stopper removed. Fig. 4. is a view of the cap removed. Fig. 5 is a perspective view ofthe reservoirvcover removed.

A represents the `floor of the oil-reservoir, A a hexagonal portion adapted for the application of the wrench, and Al a threaded por tion adapted to be screwed to the cap of a 25 journal-box or in any desired position relative to a bearing.

Ihe above parts are all integral and provided with the central vertical passage, a, for the oil.

B is a transparent tube forming the sides of the reservoir and provided at the top and bottom with suitable packing-rings, baud b', and

C is the cover. Au internally-threaded tube, I), extends centrally down from the cover C and screws upon an externallythreaded tube, E, extending up centrally from the door or base A, said tubebeing provided with perforations E', whereby the oil from the reservoir has access to the passage a. The cover C is provided with a circular central depression, C', 0n its upper side, and in the center of the depression with a perforation, O,while extending from the perforation C, along the bottom of the depression t-o its circumference, are two teats or beads, each on a line with the other, as shown in Fig. 5.

H is a tubular cap, threaded internally and provided with the serrated rim or iiange H. The bottom of this tubular cap (see Fig. 4) is provided with four radial grooves-wiz., the

5o two opposite grooves, 7L h, which are not so deep as the teats d d are thick, and the two opposite grooves, k k, which are as deep as or deeper than the said teats are thick. The grooves 7u and h are at right angles with each other.

I is a tubular valvestcm, its lower end terminating in a valve, I', its upper end provided with a serrated flange, I, and threaded cX- ternally so as to screw into the tubular cap H. The tubular portion of the valvestem is perforated at e e, in order to allow the oil to pass into the tube E. A spiral spring, J,surrounds the valve-stem and is compressed between the cover C andan annular lange,g, onthc valvestern.

L is a check-nut running on the valve-stem, and P is a stopple provided with the head P, lying in the tubular valve-stem.

To supply the reservoir, lift out the stopper P, and the oil will flow through the tubular valvestem I, the passages e e, the tube E, and the passages E E' into the reservoir. When the valve l is on its scat, asin Fig. 3, of course no oil can enter the passage a, which leads to the bearing. When the valve is in the position shown in Fig. 3, the grooves k k are directly over or coincident with t-hc teats d d, the bottom of the tubular cap Hresting on the floor of the depression C', and the valve I is forced upon its seat by the spring J, which lies 4between the langeg on the valvestem and the cover C. Now it' the cap H be rotated by means of its serrated flange until the grooves 71, h are coincident with the teats d d the valve will be raised from its seat (said grooves being shallower, as above explained) and the oil allowed to drip into the passage a. (See Fig. 1..) By turning the valve-stem in the cap the amount of drip may be exactly regulated, so that the grooves h IL may be used to supply oil, the grooves lt' k to shut it off, or the bottom of the cap lifted upon the teats d d to flood the bearing. The check-nut L holds the valvestem and cap relatively in any desired position and prevents the former from rotating independently of the latter. As the sides of the what I claim, and desire to secure by Letters Patent, is-

1. In a lubricator, the combina-tion, with a reservoir and a valve held normally therein on its seat, of the reservoir-cover C, provided with the central depression, C', surrounding the perforation C, said depression being provided on its bottom with the perpendicular radial teats or beads d, andthe cap H,provided on its under side with the radial grooves h, of less depth than the thickness of said teats or beads, and the radial grooves k, of as great as or greater depth than said teats or beads, said cap being adapted by rotation to raise said valvestem and allow the lubricant to escape from the reservoir, substantially as and for the purpose set forth.

2. The combination ofthe reservoir, consisting of the base A, provided with the passage a, tube E, and passages E', sides B and cover C, provided with the tube D, depression C, perforation C, and teats d d, the tubular cap H H,provided on its under side with the radial grooves h h k k, the two former being of less depth, and the two latter of as great or greater depth than the thickness of said teats, and the tubular valve-stein Lheld normally down upon its seat, so as to close said passage a, and provided with the perforations e e, said Valvestem being held by a eheolrnut, so as to move with the said cap as the latter rotates and rises, substantially as and for the purpose described.
